Hello!
Your "8 x 4 x 2/8 x 7" needs a bit of work to become clear. Please use " * " to indicate multiplication, not " x, " which used to represent an unknown quantity.
2
(8 x 4 x 2/8 x 7_ => (8*4*------ * 7) is my interpretation of what you typed.
8
This simplifies to (4*2*7), or (56).
Would you please treat "8^0/7^-3" in the same way. For 7^-3 please substitute:
1
7^(-3) or --------------
7^3
1
Similarly, your "7^-9" should be rewritten as 7^(-9) or -------------
7^9.
Try to get all of your exponents to be +
See what you can do with this info. If you write back I'd be happy to comment.
